An intelligent balancing strategy of influence coefficient table was presented to solve the online active balancing problem of rotor with one balancing plane and one testing point. Mathematical model of influence coefficient table method for rotor online active balancing was established in this paper, its control stability was analyzed and implementation scheme was designed. Numerical simulation of rotor single-plane single-point influence coefficient table method was carried out; the online active balancing iteration process with accurate and inaccurate initial influence coefficient cases was quantitatively given. By contrast analysis of the proposed method with adaptive and self-correcting algorithms, it is proven that the proposed method is feasible for the stable rotor, and it has the significant advantage of improving the online active balancing efficiency.
